Rousselot was born in Árbol Solo, a rural outpost in Tapenagá Department, Chaco Province, in 1935. He debuted on radio when, at age 18, he stood in for an absent broadcaster on LT5 Radio Chaco. He later worked the news daily El Territorio, and in 1958, relocated to Buenos Aires, where he joined Radio El Mundo. Rousselot hosted a talent show on Radio Rivadavia from 1964. He later became a television anchorman on a Channel 11 evening news program, El Diario Alpargatas; among his milestones at the program included live coverage of the 1969 Apollo 11Moon landing. He would be appointed spokesman for the Argentine Navy in 1972, and in 1973, for the Minister of Social Welfare and head of the Argentine Anticommunist Alliance, José López Rega. Obtaining a loan from the Ministry, he relocated to Resistencia, capital of his native Chaco Province, and purchased an ailing news daily, Diario Norte, persuading his brother, Ricardo, to join him from Chicago. He also served as director of Public Television from May to August 1975. Following the March 1976 coup, Rousselot was arrested and his newspaper was placed under provincial receivership. Its subsequent purchase by Editorial Chaco in 1978 was alleged in a 1996 lawsuit by Rousselot to have been paid with the El Norte's own profits, and at far below its market value.
Mayor of Morón
He later relocated to Mar del Plata and, in the early 1980s, to El Palomar, where he became a member of the localJusticialist Party committee. His name recognition, television experience, and marquée smile made Rousselot a natural candidate for mayoral elections in Morón, and in 1987, he was elected to the post. Rousselot became known as one of the "twelve apostles", and unsuccessfully sought the vice presidential nod when Menem was indeed nominated. He emphasized public works as mayor, initiating the construction of new streets and an extension of the sewage system, among other projects. The numerous contracts he signed for these projects became the subject of a corruption investigation by the City Council, however, and the 24-person body, voted to impeach the mayor on April 19, 1989. Rousselot was appointed Cultural Attaché at the Embassy in Paraguay. He faulted Cafiero for what he considered political persecution, and was subsequently exonerated on 28 charges related to these contracts. He ran again for Mayor of Morón in 1991, and was returned to office with 64% of the vote. He was re-elected in 1995, though ultimately the issue of city contracts would again lead to his downfall. Citing irregularities in parking meter and hospital contracts, Mayor Rousselot was again impeached on March 16, 1999, and on March 19, he was arrested at his home in Haedo. He maintained that this resulted from his opposition to Governor Eduardo Duhalde.
Later life
Rousselot was convicted in 2000 of extortion and of allocating us$225,000 for the transfer of a hospital without City Council approval, receiving a suspended sentence. Pursuant to the latter sentence, he was arrested in 2001 at the Ministro Pistarini International Airport on suspicion of attempting to flee the country. He was barred from holding public office, though never convicted of embezzlement. He later returned to radio broadcasting as a host in Radio Colonia. Rousselot developed cancer, and died in Buenos Aires in 2010.
